Open Source Makes Better Designs - Index PnP - Mobo REV03

[@stephen_hawes]

Hey gang! Thanks for all the feedback on the last video about the staging plate! Lots of excellent points, I appreciate you taking the time to share your thoughts. I totally understand that the test I ran is not providing incredibly accurate data: potential bow in the extrusion, 3D printed part tolerance, overconstraining the plate and subjecting it to warping, etc. We received actual FAI data from the vendor that serves the purpose of true data gathering. We've also found that 0.8mm is easily within the bounds of what's acceptable for this plate, given that PnP nozzles have compliance in the Z axis due to a built-in spring (but of course, the flatter the better!). I attempted to preface the data gathering with a disclaimer that this is a gut-check, a functional test, for checking the nozzle's relation to the plate in the machine, not proper metrology. I don't think I did a great job conveying this, but I'll be sure to be much more accurate and explicit in the future! However, y'all provided quite a few other ideas about how to solve this same problem easier/cheaper that we're exploring now! Some aluminum extrusion with a thin piece of steel mounted across for those interested in magnetic mounting, or plywood for those not, would be an excellent solve, and quite a bit cheaper. As always, thanks for your thoughts and feedback!

What about pcb with components in the two sides, can this pick and place be able to handled

[@C00ltronix]

@@harryman01 Not practical in a hobby setting, because part on the first side need to be glued. Otherwise they fall off in the 2nd reflow.

[@seancox3]

Can’t wait to see an index mobo populated on an index!

é sempre bom ver um português a ajudar num projecto! it's always good to see a Portuguese helping with a project! good work!

Stephen, when you're in the mood for yak shaving, put a piece of polarizing film on the webcam at your desk. The reflection of your monitor on your eyeglasses is a bit distracting, and it's easy to get rid of it since LCD light comes out polarized.

[@Graham_Wideman]

That's interesting... I'm going to have to try that. Hmmm, where can I find some polarizing film.... ::... surplus 19-inch LCD displays on the shelf looking the other way hoping not to be noticed...::

[@WurstPeterl]

Thank you! This is an absolute game changer!

[@mvadu]

You are a bundle of joy.. The happiness you radiate when it's homing is amazing.. Great progress with v3. Glad you took the expert community members to drive the board design and accept their work into yours.

[@CandyGramForMongo_]

Stephen, I believe you suffer from the opposite of depression. Well, perhaps “suffer” is the wrong word. But your positivity and joy is quite engaging. 🙂

[@JayAntoney]

Hey Stephen, any chance you recorded your interview/chat with the guy who made he board? Would love to see that video

[@OddlyIncredible]

Wheeee, got here nice and early! _Damn_ that new mobo redesign is sexy. And compact, too - packing this much functionality into 100x100mm is just nuts.

[@OhHeyTrevorFlowers]

Hey, great video and I’m really glad to see that you’re figuring out how to work in a larger community and how to encourage collaborators. That really is the strength of a big project like this.

[@AndreasBested]

The board looks really great! One small comment for the silk screen that I noticed in the video, was the naming of the bottom camera. For me, Bot Cam sounds like it might be on the gantry. Btm Cam might be clearer name wise for which camera it's referring to. Although I guess it shouldn't be hard to figure out if you are assembling an Index 😊

[@augxtino]

When you ear a Portuguese accent !!! Keep up the good work, Gonçalo and Stephen!

[@amciaapple1654]

Is there a video somewhere how he lays out this PCB in KiCAD ?

[@dancollins1012]

Great to see progress. Noting the mechanical limit switches used for homing, has their repeatability (at different homing speeds) been assessed against target accuracy? It may make sense to move to optointerrupters

[@jsamusicsociety]

Congratulations guys its is awesome! I think that Gonçalo is a Brazilian because of his accent...:-)

[@MoviePropElectronics]

I can't get modules in PCB Way store when I follow the link. Looks like something is missing.

[@xConundrumx]

Serious Question, I am going to buy a TVM802 (secondhand at a really low price). I know the vision system will have to be replaced (up and down cameras) but was wondering if your motherboard would be universal enough to use as a replacement for older machine and bring it over to OpenPNP.

[@C00ltronix]

I guess so. But be aware that the TVM802 uses three Nema 23 steppers.

[@warlockd]

So going to print the parts and try this out. Half way tempted to use my fancy closed loop stepers on it.

[@EarthlyF0rg0ten]

I used the boards to build the boards.

[@safetybeacons8124]

Is the Marlin modified source code for the Index PnP - Mobo REV03 on GITHUB

[@EndermanTheMan]

How did you learn how to design circuits boards and firmware? I’d like to learn how for my own projects.

[@Davedarko]

at this point we should ask them to just rename RS485 to RS45 :) Awesome board!

[@Graham_Wideman]

Hahahaha. Same with RS-toother-too.

[@egeoeris]

Congrats on this huge milestone! Also really diggin' the glasses.

[@realElectronicMe]

Can’t wait to see some indexes in production 🙌

[@petermuller608]

I actually switched to PCBway from jlcpcb because of you video :)

[@sajjadbabayi3704]

Can I make this circuit myself? Because I can't buy it and it can be easily made and programmed?

[@ericlotze7724]

...AND IT HAS USB-C?!? And i thought it couldn't get better lol

[@MakeItHackin]

I sincerely enjoy watching the progress of this project.

[@BrainSlugs83]

Can you talk more about your decision create yet another custom CNC board? Why not use a regular RAMPS (or GRBL) hardware (or one of the 32-bit equivalents)? You can usually pick up a completely ready to go controller board with steppers for $20 to $30 on Amazon.

[@DiyintheGhetto]

I would love to have the frame and motors where can I buy it at?

[@feldon27]

If you go into the Github repository, you can get the BOM list of parts needed and 3D prints you must do to build the Index. You may wish to wait until there is an official release that's more packaged with more detailed documentation.

[@DiyintheGhetto]

@@feldon27 will you have a buy one? And thank you.

[@feldon27]

@@DiyintheGhetto I'm going to build mine with 3D printed parts, and hand-populated circuit boards.

[@DiyintheGhetto]

@@feldon27 I would love to build one myself.

[@randycarter2001]

So how does one stay up to date when they don't do discord?

[@ramonsbb]

Great project!!! This board suport step drivers tmc5160? Because Will be great If so, for more current and velocity on moviment. Observation, tmc5160 use SPI mode STEPPER DRIVE and the board need tô som jumpe tô configure this. Thanks a Lot.

[@powil4ss]

Most breakout boards you buy these days have qwiic connector for I2C. Like all sparkfun and adafruit new boards has it. I feel like it's a must have too for anything considered to have flexibility...

[@ayanvaidya2727]

Open source hardware is going to be a very big thing in future

[@UNVIRUSLETALE]

Really cool how this is evolving

[@dmitriyv4557]

Awesome project, documentation and presentation. Thank you, Stephen! My like, comment and subscription. :) Want to see its brilliant future, and hope to buy it as a ready kit (like CNCs on Ali) one day.

[@21metalGears]

A bit of topic: Idk what changed, the beard? The glasses? But you look very handsome!

[@harryman01]

Finally , I was waiting this video for weeks

[@Mavstang73]

Any thoughts on using this board in a 3D printer with Klipper? Maybe even Marlin??? I’ve been disappointed with the quality and longevity of 3rd party boards. Designing a board is probably out of my reach. But what you’ve got here looks like it could be great in an Ender 3 or Ender 5.

[@theoldknowledge6778]

Awesome! Please make a video of it assembly unless one board… pleeease! It’s been a long way

[@stephen_hawes]

It's done some partial boards already, and some folks in the community are using it to populate boards, but in upcoming videos where I use it to make motherboards, you'll get to see it doing the full stack!

[@GoingtoHecq]

Hmm, the people who make home pcb making machines would be good at making pcbs?

[@feldon27]

PCBs are a dollar from China. Unless you need the PCB in less than 7 days, home PCB milling is not really practical. Also home milling is limited to 2 layer.

[@DIYGuitarMods]

I WANT THE PNP MACHINE NOW

[@gerbil.]

I kinda cringed at the soldering job, but very nice video! keep it up!

[@feldon27]

I so want to grab Stephen's soldering iron and run away, leaving a heat gun and solder paste in its place.

[@draco5991rep]

So you are basically saying, that you are building 3 more PNPs to build more PNPs?
